Answer:
99
Step-by-step explanation:
8 + 7(4^2 - 3)
Solve what’s in the parentheses first, starting with 4^2:
8 + 7(16 - 3)
Continue solving what’s in the parentheses:
8 + 7(13)
Considering the order of operations, multiply 7(13) before adding 8:
8 + 91 = 99
To write this equation in simplest form, we simply need to combine all like terms. The like terms in this particular expression are the terms with an n-variable and the terms with no variable. So we can combine them to simplify our expression.
5n - 6 + n - 1
First step, we can reorder our terms so that like terms are near each other
5n + n - 6 - 1
Now we can combine easily
(5n + n) - (6 - 1)
6n - 5
And that is your simplified expression.
5n - 6 + n - 1 in simplest form is 6n - 5.
Hope that helped! =)

Answer:
infinitely many
Step-by-step explanation:
i can have a rectangle whose length is extremely close to 0 (ie 1 X 10⁻⁴⁴⁴⁴⁴⁴⁴⁴)
and have an extremely wide width. But it's still a rectangle that has perimeter 60.
Biconditionals are statements that work both ways.
Some examples:
If it rains, I go out, and if I go out, it must be raining.
This can be stated concisely in mathematical terms as
I go out IF AND ONLY IF it rains.
So looking at the given statements, only the last two work both ways, namely:
If the sun rises in the east, then it is morning, and if it is morning, the sun rises in the east.
Victoria will play outside if and only if the weather is nice.
